- prehen'ds a *pile driver, in the use of which,

when one pile has been driven it will be possible to drive a second pile t'o one side of the first pile, and thendrivea third pile to the other side of the first pile; by sim ply moving the entire machine parallel therewith, Without any bakward and forward moveinent thereof.

I am aware that pile drivers have been used heretofore, which can drive more than one pile Without a 'chainge ofp'osition oi the inachinje, but in these instancesthe other piles d iven are dispo ed at angles to the first pile. With my device one or more piles can be Clill il into the ground to standabsolutely vertical; and furthermore; the main uprights 'or supporting braces are not shifted out of vertical planes, and thus the full force and efie'ct of the pile driv'ercan be obtained ivithoiit in any manner Weakening the structure, p

In the further disclosure of the inventitin, reference is to be had to the accompanying drawing. constituting a part of this specification, in which similar characters of reference denote corresponding parts iii all the views, and iii WlllClI- Figure 1 is a side elevation of the pile driver. Y i

the pile driver in its entirety is indicated by "the numeral 10, and consists substantially of a base 11, of any desired rectangular or other construction, carried on suitable cross pieces 12 which are grooved to fit rollers 13', which may be in the nature of logs, arranged to extend crosswise to the pile driver base. and upon which the entire pile driver 10 can he slid to the right or to the left, as desired. This is accoinpl'isl'ied by providing pulleys or sheaves l-l on the ends of the rollers 13; and intermediate the ends thereof, if desired, With other pulleys 15, 15 on the base of the pile driver, suitable cables 16 being passed around thep'ull'eys in the inanner shoi'vn in Fig. 2, and wound in op posits directions upon a split drum 17 on the base of the pile driver. their free ends being secured at 16 to the rollers 13, and said 'dr'uin 17 may ha \e any convenient form of connection with a suitable motor power derived from the donkey engine 18, Whereby rotation of the drum will Wind up on one cable and slack up on the other; thus as will be readily seen, pulling or sliding the pile driver 10, to the right or to the left of its initial position on the logs or rollers13, or, I may employ asingle cable 16; and a corn-cob druin in lieu of the split druni 17 In this manner. When it is desired to drive a straight row of piles, it will be clear that the piledriver 10 in its entirety can be easily moved to n w osition, to the right or left hand. to drive another pile, or another series of piles in a second row, and so on;

The base 11 supports a mainframe 19 consisting of opposed uprights 20 and supplemental uprights 21 with suitable diagonal braces22 and cross braces 23, the uprights 21 being of course vertically disposed and parallel as are also the uprights 20. said up- I rights 21 however, being arranged out- Wai'dly beyond and above; or rather to one side; of the vertical plane or the uprights 20, shown iii Fig. 1. Secured to opposed faces of the uprights 21; are hinge elements 24:, the p'intleso'f which are indicated by the numerals 25, and the hinge plates by the numerals 26, 27 g the hinge plates 26 being rigidly secured to the uprights 20. as mentioned heretofore, and the hingeplates 27 heing' rigidly secured to a supplementary or gnide fraine 28 which. in detail, cons sts of iiprightor guide pieces 29, having gu de plates. or channel irons 30. suitably secured to their inner faces, said pieces 29 and plates '30 forming the usual vertical guides or conductor for any desired or usual form of pile hammer or monkey 31, adapted to be raised and lowered upon and between the supplemental or guide frame elements, so that in its downward movement it will strike the pile and drive the pile into the ground. It will of course be seen that the supplemental or guide pieces 29, in view of their hinged connection with the main frame of the pile driver, can be swung horizontally and that normally they lie in the vertical plane of that portion of the frame of the pile driver. formed by the uprights 21, so that a cable attached to the pile hammer 31, can pass upwardly over a sheave 33 suitably journaled on the extreme upper end of the frame of the pile driver, the cable 32 then passing downwardly to be suitably wound around a drum 34, mounted on the base of the pile driver and operated by the engine 18. A second cable 32 is used for the pile fall, or for moving the piles into position for driving.

From what has been described and by reference to the drawings, it will be seen that with the machine described, a pile disposed beneath the pile hammer 31 can be readily driven down into the ground, by the action of the pile hammer 31 thereon. Now, when a pile has been so driven. instead of moving the entire pile driver 10, to rearward and then forward, to drive the next adjacent pile, it is only necessary to swing one of the supplemental or guide pieces 29 upon its hinges 24, in order to bring the supplemental or guide frame 28 into a position to one side of the driven pile so that the new pile can be driven by the pile hammer 31, into the ground adjacent to the driven pile, this operation being accomplished by simply moving the entire pile driver 10 by rotating the split drum 17 in the desired direction. And so also the other supplemental or guide piece 29, can be swung to the other side of the first driven pile, and a third pile driven by the pile hammer into the ground ajacent and to the other side of the first driven pile. In order to retain the supplemental or guide frame 28 in a stationary position, or in alinement with the uprights 21, there are provided a plurality of locking elements or pins 35, each of which is mounted to slide vertically in suitable supports or guides 36, arranged upon the uprights 21, and in a similar guide 7, for each pin 35, secured to the supplemental or guide pieces 29, and through which the pin is adapted to pass, it being thus seen that the supplemental or guide frame 28, when the pins 35 are both in locked position, will be held against the horizontal swinging movement. Each pin 35 has a crosspin or projection 38, which,

into place.

when the pin is raised to disengage the latter from the guide plate 37, will strike the upper guide plate or support 36 and thus limit the upward movement of the pin, as will be clearly understood by reference to Figs. 1 and 5. A suitable cable or light chain'39 is connected to each pin 35, and passing over a pulley 40 on the upright 21, connects with the drum d1 of the donkey engine, so that the pin can be mechanically raised when desired. Now it will be clear that after the first pile has been driven and it is desired to drive a second pile to the right of the first, it is only necessary to move the right-hand pin 35 into unlocked relation with the guide frame, so that the guide piece 29 can be swung to the right and be re-disposed in the necessary vertical position to permit of the monkey 31, operating upon the right-hand pile to drive the latter And thus after this has been accomplished, the other supplemental or guide piece 29 can be similarly swung to drive the lefthand pile and the unlocked pin 35 permitted to gravitate back into locked relation with the guide frame 37. In order to more securely lock the guide pieces 29 in position, I preferably extend the lower hinge elements 27, at -12, and fashion them into eye pieces 43. for cooperation with eye pieces 44, secured to the uprights 20, pins being employed for locking the parts l3, 44 together; short chains 46 are attached to the pins 45 and to the uprights 20, for preventing the accidental loss of said pins when the parts are unlocked.

From the foregoing description it will be seen that with the form of construction described, a row of piles can be rapidly driven by the pile driver without moving the body of the same backward and forward as heretofore, and in accomplishing this result, no part of the frame work, namely, the uprights, is moved from a vertical plane, and furthermore, the piles that are driven are operated upon from a vertical position so that they will be vertically and not angularly driven into the ground, and will, when driven, be disposed substantially parallel to each other.

I claim:

1. A pile driver comprising a base, a framework on the base, vertically disposed guide members mounted to swing horizon tally on the framework, a pile hammer slidingly disposed on the guidemembers, and means for normally holding the guide mem bers against said horizontal swinging movement.

2. A pile driver comprising a base, a framework on the base, vertically disposed guide members mounted to swing horizontally on the framework, a pile hammer slidingly disposed on the guide members, and

means for normally holding the guide members against said horizontal swinging movement, said means holding said guide members in the vertical plane of the base and framework.

3. A pile driver comprising a base, a framework on the base, a vertically disposed horizontally swinging guide frame on said framework. a pile hammer operable in said guide frame, and removable looking pins holding said guide frame against horizontal swinging movement.

4:. A pile driver comprising a base, a framework on the base, guide members mounted to swing on the base, and normally adapted to lie in the vertical plane of the framework, said guide members being movable horizontally to one side or the other of their normal position, said guide members being at all, times vertically disposed, and means for locking said guide members against any horizontal swinging movement.

In testimony whereof I aflix my signature.

JOHN TORJESEN.
